Have you ever woken up in the morning and looked in the mirror and suddenly noticed that your eyes are red? Or have you had some discomfort or itching in your eyes all day long? This is what we usually call 'red eye'. This is actually a very common condition that many people experience at some point in their lives. So there is nothing to be afraid of. Let's talk about this in simple terms today.
What exactly does this reddening of the eyes mean?
Simply put, 'red eye' is a general term used to describe a red, slightly swollen, and uncomfortable eye. This redness is caused by the tiny blood vessels in the white part of our eye (the sclera) becoming enlarged or inflamed for some reason. To be precise, this is the eye's response to something irritating it.
This can cause one or both eyes to become red. Sometimes it can happen suddenly, and other times it can happen gradually. Along with red eyes, you may also experience other symptoms, such as:
- Eye pain
- Itchy eyes
- Eye discharge or discharge
- Swollen eyes
- Vision changes, such as blurred vision
Are red eyes always serious?
Most of the time, red eyes are not as serious as they seem . In fact, most cases are harmless and resolve within a few days with home remedies or over-the-counter eye drops.
However, if your red eyes last more than a week , or if you have eye pain or vision problems , you should definitely see your doctor . Sometimes red eyes can be a symptom of another serious condition.
What are the main causes of red eyes?
There are many reasons why your eyes may become red. Sometimes, your eyes may become red when you wear contact lenses for a long time, or when you stare at a computer screen for a long time. Let's look at some of the most common reasons.
| Cause | A simple description |
|---|---|
| Allergies | When our eyes react to things around us like dust, smoke, pollen, and pet dander. |
| Eyelid infections (Blepharitis) | A swelling or infection of the eyelid margin. This can cause itching, redness, and crusting of the eyelid. |
| Eye diseases (Conjunctivitis) | This is what we commonly call 'eye disease'. It can be caused by a viral or bacterial infection. It is highly contagious. |
| Dry Eye | When the eyes do not produce enough tears, they become dry, red, and inflamed. |
| Eye injuries | When something hits the eye or causes a scratch, the blood vessels that supply blood to the eye dilate and the eye becomes red. |
| Glaucoma | This is a serious condition. The pressure inside the eye can increase, damaging the optic nerve. In a case of acute glaucoma, the eye becomes red, causing severe pain and blurred vision. |
What things can you do at home?
Most of the time, if your eyes are red for a simple reason, you can get relief by doing these things:
- Rest: Give your eyes a break. Especially reduce the amount of time you spend looking at the computer or phone.
- Cold compress: Soak a clean cloth in cold water, close your eyes, and place it over them for a few minutes.
- Eyelid cleaning: If there is crusting around the eyes, gently wipe them with a cotton ball soaked in clean water.
- Over-the-counter eye drops: You can use things like artificial tears, which you can buy at the pharmacy, after consulting your doctor. However, do not put any medication in your eyes without consulting a doctor.
In some cases, your doctor may prescribe eye drops or ointments containing antibiotics for an infection, or other special medications for allergies.
Can red eyes be prevented?
While it is not possible to prevent every situation, these things can help reduce the risk:
- Don't rub your eyes: Germs and dirt on our hands can get into your eyes and make the condition worse.
- Keep contact lenses clean: Do not wear them for longer than the recommended period.
- Remove eye makeup properly: Clean your makeup thoroughly before going to bed at night.
- Take breaks when looking at the computer: Every 20 minutes, look at something about 20 seconds away (20-20-20 rule).
- Avoid allergens: Stay away from things that cause you allergies, such as dust, smoke, and pet dander.
- Wash your hands thoroughly: This can prevent many contagious infections, such as eye infections.
When should you see a doctor?
If the redness of the eyes does not usually go away within a couple of days, or if a young child has red eyes, it is best to call a doctor. It is especially important to seek medical advice immediately if you have any of the following symptoms:
| Warning signs that require immediate attention | |
|---|---|
| Severe eye pain | If you feel pain that is more severe than a simple discomfort. |
| Vision changes | If your vision is blurry, double vision, or difficulty seeing. |
| Sensitivity to light | If your eyes feel too uncomfortable to look at normal light. |
| Excessive discharge from the eye | If you have a thick green or yellow discharge or if your eyes are so congested that you can't open them in the morning. |
| Fever or body aches | If these symptoms are present along with red eyes. |
| After an eye injury | If something gets in your eye or gets scratched, see a doctor immediately. |
